At the moment there are several types of crypto wallets. If I'm not mistaken, some of them are called hot (those that are confined to the Internet), and others - cold, not dependent on the Web. At the same time, hot ones are divided into online wallets, as well as mobile and desktop ones. These will suit you for currency trading, small transactions and buying cryptocurrency. But if you are going to invest in cryptocurrency and store valuable assets and important information on it, then it is better to choose cool hardware wallets https://entheca.com/ .
